The Emperor Wears No Clothes is a non-fiction book written by Jack Herer. Starting in 1973, the story begins when Herer takes the advice of his friend, “Captain” Ed Adair, and begins compiling tidbits of information about the Cannabis plant and its numerous uses,[1] including as hemp and as a drug. After a dozen years of collecting and compiling historical data, Herer first published his work as The Emperor Wears No Clothes, in 1985. The twelfth edition was published in November 2010,[2] and the book continues to be cited in Cannabis rescheduling and re-legalization efforts.[citation needed]

If all fossil fuels and their derivatives, as well as trees for paper and construction were banned in order to save the planet, reverse the Greenhouse Effect and stop deforestation; then there is only one known annually renewable natural resource that is capable of providing the overall majority of the world’s paper and textiles; meet all of the world’s transportation, industrial and home energy needs, while simultaneously reducing pollution, rebuilding the soil, and cleaning the atmosphere all at the same time… and that substance is — the same one that did it all before — Cannabis Hemp… Marijuana!

European expert on hemp and author of the doctoral thesis Crop physiology of fibre hemp (1994), Dr. Hayo M.G. van der Werf criticized the book for containing some inaccuracies, stating, “Although most of the information contained in the book is valid, some of its claims are clearly incorrect.”[3]
